Re: [EnergyPlus_Support] Defining an Interior Surface in Airflow Simulation
1. For any interzone surface or subsurface, you have the option of describing
only one instance and setting the OutsideFaceEnvironment Object =
UnenteredOtherZoneSurface. EnergyPlus then automatically generates the
mirrored instance of this surface in the adjacent zone.
2. If I'm reading it correctly, that text is referring to adiabatic surfaces
(where the surface refers to itself as the other side object). This needs
clarification. This is not a new restriction.
I assume you are aware that large horizontal openings cannot be modeled well.
See guidance under "AirflowNetwork:Multizone:Component Detailed Opening" in the
Input Output Reference.
